45# High-Quality Carbon Structural Steel Wire Rod

WongSteel 45# High-Quality Carbon Structural Steel Wire Rod is a core raw material product launched by Beijing Yijing Technology for medium-high strength wire processing. It strictly follows the **GB/T 4354** national standard, featuring two main specifications of 5.5mm and 6.5mm. Specially designed for high-demand wire drawing, cold heading and product manufacturing scenarios, it is a key base material for medium-carbon high-quality steel wire deep processing.

The core advantages of the product lie in its **excellent microstructure and properties**: the decarburization layer is precisely controlled with minimal thickness, preventing performance degradation during subsequent heat treatment and wire drawing from the source; the inclusion content is extremely low with controllable morphology, ensuring the internal uniformity of the material and improving wire breakage control during drawing. The **high sorbite rate** is its core feature. The sorbite structure endows the wire rod with excellent plasticity, ductility and drawing performance, enabling uniform deformation and low springback of the wire during continuous drawing. It can be stably processed into fine-specification wires, while achieving excellent strength and toughness matching, meeting the mechanical requirements of various high-end hardware products.

Thanks to the balanced grain size and excellent processing performance, 45# wire rod can be widely used in **construction, agriculture, transportation, furniture** and other fields. Specifically, it can be processed into nails, steel wire ropes, civil greenhouse wires, brake cables for bicycles and e-bikes, and spokes (spoke). In the production of steel wire ropes, its high toughness and high strength characteristics can ensure the bearing capacity and fatigue resistance of the mesh body; in the production of safety parts such as brake cables and spokes, it can be further strengthened through subsequent heat treatment to meet the stringent strength and durability requirements, adapting to the use needs of high-end transportation vehicles and infrastructure wires.

Relying on WongSteel's full-process quality control system, strict inspection is carried out in every link from smelting, continuous casting, rolling to finished product delivery to ensure the stable consistency of composition, structure and properties of each batch. We provide one-stop services from raw material supply, customized specification adjustment to logistics supporting, supporting small-batch samples and large-batch long-term orders, building an efficient supply chain for enterprises in fasteners, steel wire ropes, transportation accessories and other fields, helping enterprises improve product quality and market competitiveness.
